Different rotamer states of cytosine nucleobases in heteronuclear PtPd-, PtPd2, and Pt2Pd2Ag complexes derived from [Pt(2,2?-bpy)(1-MeC- N3)2]2+ (1-MeC = 1-methylcytosine): First examples of species with head-head oriented 1-MeC – ligands

[Pt(2,2?-bpy)(1-MeC-N3)2](NO3)2 (1) (2,2?-bpy = 2,2?-bipyridine; 1-MeC = 1-methylcytosine) exists in water in an equilibrium of head-tail and head-head rotamers, with the former exceeding the latter by a factor of ca. 20 at room temperature. Nevertheless, 1 reacts with (en)PdII (en = ethylenediamine) to give preferentially the dinuclear complex [Pt(2,2?-bpy)(1-MeC–N3,N4) 2Pd(en)](NO3)2¡¤5H2O (2) with head-head arranged 1-methylctosinato (1-MeC-) ligands and Pd being coordinated to two exocyclic N4H- positions. Addition of AgNO 3 to a solution of 2 leads to formation of a pentanuclear chain compound [{Pt(2,2?-bpy)(1-MeC-)2Pd(en)} 2Ag](NO3)5¡¤14H2O (5) in which Ag+ cross-links two cations of 2 via the four available O2 sites of the 1-MeC- ligands. 2 and 5 appear to be the first X-ray structurally characterized examples of di- and multinuclear complexes derived from a Pt II species with two cis-positioned cytosinato ligands adopting a head-head arrangement. (tmeda)PdII (tmeda = N,N,N?,N?- tetramethylethylenediamine) and (2,2?-bpy)PdII behave differently toward 1 in that in their derivatives the head-tail orientation of the 1-MeC- nucleobases is retained. In [Pt(2,2?-bpy)(1-MeC -)2{Pd(2,2?-bpy)}2](NO3) 4¡¤10H2O (4), both (2,2?-bpy)PdII entities are pairwise bonded to N4H- and O2 sites of the two 1-MeC- rings, whereas in [Pt(2,2?-bpy)(1-MeC-) 2{Pd(tmeda)}2(NO3)](NO3) 3¡¤5H2O (3) only one of the two (tmeda)Pd II units is chelated to N4H- and O2. The second (tmeda)PdII is monofunctionally attached to a single N4H- site. On the basis of these established binding patterns, ways to the formation of mixed Pt/Pd complexes and possible intermediates are proposed. The methylene protons of the en ligand in 2 are special in that they display two multiplets separated by 0.64 ppm in the 1H NMR spectrum.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 14871-92-2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14871-92-2, in my other articles.

Toppled molecular-domino sets by self-assembly of self-assembly: The pi-polymers

A series of designed binuclear palladium(II)-based self-assemblies, [Pd2(en)2(L)2](NO3)4, 1a; [Pd2(tmeda)2(L)2](NO3)4, 2a; [Pd2(bpy)2(L)2](NO3) 4, 3a; and [Pd2(phen)2(L)2](NO 3)4, 4a, are synthesized. These complexes are obtained in good to excellent yields by equimolar combination of the nonchelating bidentate ligand bis(4-pyridylmethyl)piperazine, L, with the corresponding cis-protected palladium(II) component, that is, Pd(N-N)(NO3)2, under suitable reaction conditions. The cis-protecting N-N units used are ethylenediamine (en), tetramethylethylenediamine (tmeda), 2,2?-bipyridyl (bpy), and 1,10-phenanthroline (phen). The complexes 1a-4a are well-characterized by 1H NMR, H-H COSY, and HSQC, and the molecular compositions have been established by ESI-MS. The molecular structures are confirmed for the complexes [Pd2(tmeda)2(L) 2](ClO4)4, 2b; [Pd2(bpy) 2(L)2](ClO4)4, 3b; and [Pd 2(phen)2(L)2](NO3)4, 4a, by the single-crystal X-ray diffraction technique. In the cases of the complexes 3b and 4a, the crystal packing diagrams display a unique one-dimensional predefined organization of molecules by intermolecular pi-pi interactions using the strategically located pi-surfaces of the cis-protecting units. This organization resembles a set of toppled dominos. A given set exhibits further interactions with the neighboring sets in the packing pattern that are influenced by the nature of the N-N moiety, for example, bpy or phen. However, no such arrangement is observed in the case of the complex 2b due to the lack of a pi-surface at the cis-protecting moiety.

Platinum(II)- and palladium(II)-amide complexes [M{NC(O)CH2CH2}2L2] derived from 2-azetidinone (beta-propiolactam); a synthetic, electrospray mass spectrometric and X-ray crystallographic study

A number of platinum(II) and palladium(II) complexes 3 and 4 containing amido ligands derived from beta-propiolactam (2-azetidinone, Haz) havebeen synthesized in high yield by the silver(I) oxide-mediated reaction s of the complexes cis-[MCl2L2] [M = Pt, L = cycloocta-1,5-diene (COD) or PPh3; M = Pd, L = 2,2′-bipyridine (BIPY) or 1,10-phenanthroline (PHEN)with 2-azetidinone. Displacement of the COD ligand allowed the synthesi s of a number of other derivatives containing phosphine, phosphite and isocyanide ligands. Electrospray mass spectrometry has also been used to further characterize these complexes, to probe the strength of binding of the amide ligands and to investigate the ability of the complexes to act as metallo-ligands towards other mono-, di- and trivalent cations. A detailed study on the bis(triphenylphosphine)platinum complex 3b shows that fragmentation, induced by higher cone voltages, proceeds initially via loss of a deprotonated azetidinone monoanion (az(-)) ligand, yielding[Pt(az)(PPh3)2](+). Upon further increasing the cone voltage, cyclometa llation of one of the triphenylphosphine ligands occurs. Complex 3b readily forms adducts with a range of alkali-metal cations, Ag(+), divalent cations (Ba(2+), Cu(2+), Zn(2+) and Pb(2+)) and a trivalent cation (Pr(3+)). Complex 3b shows selectivity for Na(+) ions over other alkali-metalcations in forming a dipositively charged aggregate of the type [2M*2Na ](2+) at low cone voltages. The X-ray structure of complex 3b is also reported.

1H NMR spectroscopic identification of binding modes of 2,2?-bipyridine ligands in complexes of square-planar d8 metal ions

The reaction of [M(bpy)]2+ (M = PdII and/or Pt II; bpy = 2,2?-bipyridine) moieties with model nucleobases leads to a variety of products, viz. 1: 1, 1: 2 and 2: 2 (head-tail, ht, or head-head, hh) complexes. By carefully analysing the H5 (H5?) resonances of the bpy ligands, which in all cases occur furthest upfield, and with additional indicators (concentration dependence of H6, H6? resonances; 195Pt-1H coupling constants, if observable; absolute shifts of H5, H5?), it is possible to assign binding situations of bpy ligands, even in multinuclear complexes with several [M(bpy)]2+ entities in different environments present. The analysis presented here is carried out on X-ray structurally established cases of [M(bpy)]2+ complexes, including three new ones, [Pt(1-MeC-N3)2(bpy)](NO 3)2¡¤2.5H2O (5), ht-[(bpy)Pd(N3-1- MeC–N4)2Pd(bpy)](ClO4)2¡¤ 3H2O (16) and ht-[(bpy)Pd(N1-ampy–N2)2Pd(bpy)] (NO3)2¡¤3H2O (17). The data provide a consistent picture, useful for the future assignment of similar bpy complexes in the absence of X-ray structural evidence. The Royal Society of Chemistry 2009.

New zinc(II), palladium(II) and platinum(II) complexes of dl-piperidine-2-carboxylic acid; X-ray crystal structure of trans-[Zn 2(mu-Ca)2(Hpa)2Cl6] and anticancer activity of some complexes

New complexes of dl-piperidine-2-carboxylic acid (dl-H2pa), [Zn(Hpa)(AcO)(H2O)2], trans-[Zn2(mu-Ca) 2(Hpa)2Cl6], [M(bpy)(Hpa)]Cl and [M(pa)(PPh3)2] (M(II) = Pd, Pt) have been prepared and characterized on the basis of elemental analyses, molar conductivity and thermal measurements, IR, Raman, UV-Vis, NMR (1H and 31P) and mass spectroscopy. dl-Piperidine-2-carboxylic acids act as bidentate ligands, through the carboxyl oxygen and cyclic nitrogen atoms. The crystal structure of trans-[Zn2(mu-Ca)2(Hpa)2Cl6], obtained from the addition of ZnCl2 to dl-H2pa in either hard tap water or presence of CaCl2, has been determined by X-ray diffraction. It crystallizes in a triclinic lattice with space group symmetry P1. The complex has two zinc atoms in tetrahedral geometry, each ligated by a carboxyl oxygen and three chlorine atoms. The other carboxyl oxygen atoms from the two Hpa- ligands are bridged by two calcium atoms, i.e., there are two Zn(Hpa-)Cl3 units bridged by two calcium atoms. The free dl-H2pa and its complexes, trans-[Zn2(mu-Ca) 2(Hpa)2Cl6], [Pd(bpy)(Hpa)]Cl and [M(pa)(PPh3)2] (M(II) = Pd, Pt) have been tested against the serous ovarian cancer ascites, OV 90 cell line.

Optically active sulfur-bridged Co(III)-M(II) (M = Pd, Pt) dinuclear complexes with square-planar [M(mu-S)2(bpy)] (bpy = 2,2?-bipyridine) frameworks derived from octahedral bidentate sulfur-donating Co(III) metalloligands

The reactions of the optically active octahedral mononuclear complex, trans (N)-[Co(D-pen)2]- (D-pen = D-penicillaminate), with [PdCl2(bpy)] (bpy = 2,2?-bipyridine) and [PtCl2(bpy)] stereoselectively gave the S-bridged dinuclear complexes, [Pd(bpy){Co(D-pen)2}]+ (1a) and [Pt(bpy){Co(D-pen)2}]+ (1b), respectively. A similar optically active S-bridged dinuclear complex, Delta-[Pt(bpy){Co(aet)2(R-pn)}]3+ (2b; aet = 2-aminoethanethiolate, pn = 1,2-propanediamine), was also obtained by the substitution reaction of DeltaDelta-[Ni{Co(aet)2(R-pn)}2]4+ with [PtCl2(bpy)]. The crystal structures of 1a, 1b, and 2b were determined by X-ray crystallography, and compared with that of the previously reported Delta-[Pd(bpy){Co(aet)2(R-pn)}]3+ (2a). The Co(III) equatorial planes and the PdN2S2 or PtN2S2 square planes in the 1a and 1b are almost coplanar, while those in 2a and 2b are somewhat bent from each other. In addition, the distortions from the square planes to tetrahedrons in 2a and 2b are more pronounced than those in 1a and 1b. Furthermore, all of the bridging S atoms in 1a and 1b are stereoselectively unified to the S configuration, in contrast to those in 2a and 2b with the R configuration. These reflect the differences of the optically active Co(III) units in these complexes. The complexes. The electronic absorption, CD, and 13C NMR spectral behaviors of these complexes are also discussed in relation to their crystal structures.

Palladium complexes with the SC6F4H-4 ligand – Synthesis, spectroscopy, and structures

The reaction of HSC6F4H-4 or KSC6F 4H-4 with the palladium(II) complexes [(NN)PdCl2] [NN = 2,2?-bipyridine (bpy) or 1,10-phenanthroline (phen)] leads to the mononuclear palladium complexes [(NN)Pd(SC6F4H-4) 2] or [(NN)PdCl(SC6F4H-4)], whereas the reaction with [(COD)PdCl2] (COD = 1,5-cyclooctadiene) results in the loss of COD and the formation of the oligonuclear species [Pd(SC 6F4H-4)2]m. For NN = phen, the compound [(phen)2K(mu-phen)2K(phen)2][(4- HC6F4S)2Pd(mu-SC6F 4H-4)2Pd(SC6F4H-4)2] containing a homoleptic dimeric dianionic Pd complex was also obtained. The reaction of KSC6F4H-4 with PdCl2 yielded K 2[Pd(SC6F4H-4)4]. The new compounds were analysed and characterised by single-crystal XRD, 1H and 19F NMR spectroscopy and IR spectroscopy. The UV/Vis absorption spectroscopy and electrochemistry of [(bpy)Pd(SC6F 4H-4)2] have been investigated and are compared to those of the related Pt derivative [(bpy)Pt(SC6F5)2]. Preparation routes to palladium(II) complexes with the SC6F 4H-4 ligand and their structures and spectroscopy have been studied by single-crystal XRD, multinuclear NMR spectroscopy, UV/Vis absorption spectroscopy, and electrochemistry.
